Love JavaScript Challenge

The month of love is over. Some of us celebrated the valentines, some didn’t. At Developers in Vogue, we decided to show love in the best way we know how. A challenge was organized for the community and was posted on Twitter.

[Tweet “I love coding. I also loved the prize and was going to do my best to get it. Guess what? I did!! In this post, I will show you how I worked on the challenge.”]

Reuse can result in transmission of bloodborne pathogens (including HIV and hepatitis), potentially endangering patients and health care providers. Tell your doctor if you use any type of steroid medicine such as cortisone (Cortef, Cortone), methylprednisolone (Medrol), prednisone (Deltasone, Orasone), prednisolone (Prelone, Pediapred), and dexamethasone (Decadron). COBI may be used as a boosting agent in children weighing ≥40 kg and adults farmaciasonline.org. Famciclovir has not been studied in patients with severe hepatic impairment.

For the styling, I started by giving the body background colour. I decided to go with gradient colours since they are recently rocking in the design community. I used a tool called UIGradient to generate the colour. UIGradient has a range of colour gradients and I decided to go with “King Yna”.

I wanted all my elements in the middle. So I created a div container with a class heart, the aligned the class and its text in the middle.

The Count Down Timer

First, create a countDownDate variable which holds the time to the count down date. The getTime() method from Date() object in javascript gets time in milliseconds since January 1, 1970.
var countDownDate = new Date(“Feb 14, 2019 00:00:00”).getTime();

Then get the current time in milliseconds and store in variable now.
var now = new Date().getTime();

To get the time difference between the count down date and the current time, take var countDownDate minus var now. The result of the difference is in milliseconds and is stored in a variable called distance.
var distance = countDownDate — now;

The next step is to convert distance(which is time difference in milliseconds) to days, hours, minutes and seconds and then display the result on the HTML page.
var days = Math.floor(distance / (1000 * 60 * 60 * 24));
var hours = Math.floor((distance {52e84c63bcc1991aaa809f9fdca0ba526b664e9b34f7b3d4b9b1c6537e52df15} (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
var minutes = Math.floor((distance {52e84c63bcc1991aaa809f9fdca0ba526b664e9b34f7b3d4b9b1c6537e52df15} (1000 * 60 * 60)) / (1000 * 60));
var seconds = Math.floor((distance {52e84c63bcc1991aaa809f9fdca0ba526b664e9b34f7b3d4b9b1c6537e52df15} (1000 * 60)) / 1000);

document.getElementById(“theTimer”).innerHTML = days + “d “ + hours + “h “ +minutes + “m “ + seconds + “s “;

To make sure negative days are not displayed, check whether the countDownDate is passed by checking whether the distance is less than zero. If it the count down date is in the past, “EXPIRED” is displayed in the place of time remaining to the count down date.
if (distance < 0) {
clearInterval(x);
document.getElementById(“theTimer”).innerHTML = “EXPIRED”;
}
}

Valentines Day Quiz

I used a form to implement the quiz. The form is displayed only after clicking the “Take Quiz” button. I therefore, make the button and the modal that contain the form accessible to JS by creating the variables, btn and modal as follows:
var modal = document.getElementById(‘myModal’);
var btn = document.getElementById(“myBtn”);
